Abstract

PROBLEM TO BE SOLVED: To provide a disk case which can be used, instead of a conventional type of CD case, for housing selectively either a single body of a disk or a disk cartridge only by changing means of use for a tray. SOLUTION: While a center fixing part for fixing the center of a single body of the disk is provided at the center at the inside of the tray, fixing parts for fixing a plurality of small cartridges for housing in the tray are provided around the aforementioned center fixing part on positions not interfering the housing of the single body of the disk.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a case for storing a disk and a cartridge.

[0002]

2. Description of the Related Art Conventionally, as in Japanese Utility Model Registration No. 3042539, a plurality of small memory cartridges can be stored in a CD-size case at the same time, or as in Japanese Patent Application Laid-Open No. 11-208759. A case that can simultaneously store an MD cartridge and a CD is known.

[0003]

However, in the former case, since the case is reserved because the cartridge is exclusively used, it is not versatile to use the case. Therefore, both cases for the CD and the cartridge are required. Space is needed. In the latter case, since the shape for fixing the CD to the cover is formed, the index card cannot be stored in the cover when the CD is stored, and both the bottom plate and the cover need to be changed. On the other hand, there was a problem on the producer side, such as a completely different product, and a large investment burden on production dies.

On the other hand, in recent years, several cartridges containing a small-diameter disk of about 2 inches have been proposed. However, if the cartridge of this size is rectangular, a case design in which only four cartridges are arranged in a CD case is required. However, there is also a problem that the entire surface of the case is almost completely buried, and a fixing portion for the CD center hole for mounting a CD cannot be provided.

[0005] The present invention has been made based on the above circumstances, and requires only a minimum change from a conventional CD case to a CD.
It is an object of the present invention to provide a dual-purpose case capable of selectively storing a plurality of cartridges each containing a single unit or a 2-inch diameter disk and improving the storage of other types of media.

[0006]

Therefore, in the present invention, in recent years, Japanese Patent Application Laid-Open Nos. 11-353845 and 11-2
As described in JP-A-60016 and JP-A-11-110945, attention has been paid to the fact that a large notch is provided at a corner portion of a cartridge accommodating along the shape of a built-in disk. A center fixing portion for a single CD disk is provided at an inner center, and a fixing portion for accommodating a plurality of small cartridges around the center fixing portion at a position where there is no hindrance to accommodating the single CD disk. Provide what you are equipped with.

[0007] As a result, a single disk and a cartridge can be selectively accommodated by changing only the tray to a special configuration with respect to the conventional CD case.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described specifically. FIGS. 5 and 6 show an example of a cartridge conforming to the present invention. In this case, the cartridge 5 is notched in a large arc shape close to a disk shape in which at least one corner portion 5a is built in, with respect to a square shape. In addition, positioning holes 5b and 5c for mounting on the apparatus are provided at two corners without a notch. Reference numeral 5d denotes a known shutter that slides when the apparatus is mounted and forms an opening for head access for recording and reproduction and fitting of a turntable.

FIGS. 1 to 4 show an example of the case of the present invention. The case here has a flat rectangular flat outer shape having the same shape as a conventionally known CD case, and includes a case main body 1 and a lid 2. The case body has a bottom plate 3 and a resin tray 4 attached thereto. The tray 4 has a structure substantially similar to that of a CD case and is detachably attached to the inside of the bottom plate 3.

The tray 4 has a well-known cylindrical projection 4a which is engaged with and fixed to the center hole of the disk unit 6 at the center.
Are formed. Similarly to the CD case, the tray 4 has a raised portion around the occupied portion 4c of the disk unit 6, and the raised portion 4b avoids the escape portion 4d of the index accommodating claw of the lid, and also has a disk cartridge. A digging 4e having substantially the same depth as the single disk occupying portion 4c is formed in a shape in which a wall of the corner having the positioning hole is substantially shaped.

When the cartridge 5 is arranged in accordance with the wall of the dug portion 4e, the above-mentioned cylindrical projection 4a is located in the notch 5a of the cartridge 5, as shown in FIG. Further, a shaft portion 4f is formed in a portion of the dug portion 4e where the positioning holes 5b and 5c of the cartridge 5 are located. As shown in FIG. 4, the shaft portion 4f has a slit, and the distal end portion diameter is slightly enlarged (undercut).

In the above-described configuration, the disk unit 6 can be engaged with the cylindrical projection 4a with the center hole in the same manner as in a normal CD case, and can be stored in the inside 4c of the case (see FIG. 3). Further, it is also possible to insert the shaft 4f into the positioning holes 5b and 5c of the cartridge in accordance with the digging shape 4e to house a plurality of cartridges 5 (see FIG. 2).

At this time, since the cartridge 5 is positioned by the shaft 4f and is prevented from rotating by the wall of the dug portion 4e, it does not move in a plane. In addition, when fitting into the cartridge positioning holes 5b, 5c, the width of the shaft portion 4f is reduced and deformed by the slit portion and is prevented from falling off by the elasticity of the resin, so that it does not move in the height direction.

In the height direction, according to the thickness of the cartridge 5, the shaft is simply formed into a cylindrical shape, and the cartridge 5 is sandwiched between the tray surfaces 4c and 4e and the lower surface of the lid 2 to suppress the floating. It is good also as a form to do. Also,
If the mounting position shape of the cartridge is marked on the 4c surface in a scribble shape, it becomes a guide for mounting the cartridge and the usability is improved.

If the thickness of the cartridge is close to the distance between the bottom plate and the lid, as shown in FIG. 7, in the above-described embodiment, the outer portion of the tray 7 when the cartridge is arranged is cut out to form a hole 7a. Alternatively, the cartridge may be fitted therein.

[0016]

According to the present invention, the conventional C
With respect to the D case, a single disk and a cartridge can be selectively housed only by changing the use form of the tray, and versatility can be secured.
